Halloween is the perfect time of year to use dry ice to make your party or event extra spooktacular! Check out some of these great projects to learn how you can liven up your Halloween in 2018 – just be sure you and your kids follow dry ice safety precautions.

Our convenient locations in Buffalo and Rochester (see the bottom of this page) have enough dry ice to make your house the hit of the trick-or-treat circuit.

Bring your kids in to see live demonstrations – and don’t forget to pick up some dry ice for your 2017 Halloween Party!

Dry Ice Witch’s Cauldron

A large container
Hot water
Dry ice
Make sure to follow all dry ice safe handling precautions.

Fill a metal or plastic container half full of hot water and add a few pieces of dry ice every 5-10 minutes. As the water cools, you will need to add more hot water to maintain the fog effect. As a rule of thumb, one pound of dry ice will create 2-3 minutes of fog effect. The hotter the water, the more fog, but the quicker sublimation of the dry ice.

When you place dry ice into warm or hot water, clouds of white fog are created. This white fog is condensed water vapor, mixed in with the invisible CO2. The extreme cold causes the water vapor to condense into clouds. The fog is heavy, being carried by the CO2, and will settle to the bottom of a container. This can be poured out and produce enough fog to fill a medium-sized room with a pound or so of dry ice. Do not allow anyone (including pets) to lie in this fog because too much CO2 is unsafe.

Dry Ice Jack-O-Lantern

To create the Spooky Halloween Jack-O-Lantern with dry ice fog, you will need:

A large pumpkin
A small bowl
Hot water
Dry ice
Make sure to follow all dry ice safe handling precautions.

Choose a pumpkin large enough to hold a small bowl inside. Clean out the pumpkin and carve a friendly or a frightening face. Keep in mind, carbon dioxide fog sinks so more fog will flow out of the bottom.

When you are done cleaning out and carving your pumpkin, fill a small bowl about half full with hot water and mix in a cup of salt (optional).

Place the bowl inside of the pumpkin. Wearing thick gloves, drop two or three large pieces of dry ice into the bowl of water and cover the top of your pumpkin. Make sure the lid fits tightly to eliminate air currents dissipating the fog. As the water cools, add more hot water to maintain the fog effect. As a rule of thumb, one pound of dry ice will create 2-3 minutes of fog effect. The hotter the water, the more fog, but the quicker dissipation of the dry ice.
